cat question

My main concern is passing emmisions and not having my check engine light on. I'm nervous that if I hollow out the cats (destroying them) that later on my light will come on, and I'll have to buy new cats or simulators; and I probably wont haqve any extra cash to buy anything mod-wise for awhile.
